Support SSH through SOCKS proxy

[davidrg]

Kermit 95 2.1.3 should do it, so 3.0 ought to as well. The implementation needs to go into ssh_open_socket(char*,char*) in ckossh.c.

The old version of ckossh.c likely has the required code. Looks like you just call various SOCKS functions rather than the regular ones (eg, SOCKSconnect instead of connect):
